Supra_87_mk3 is on a distinguished road
Default

every turbo has a speed that it can spin w/o damaging it's self and if it free spins faster than that speed the shaft will flex cousing it to hit the wall of the turbo.... thus a bent shaft...i think when i was hitting what felt like fuel cut. it must have free spun...
